Fit & Unfit Boundaries

Ideal For

  • Outdoor 10kV distribution networks
  • Three-phase metering and protection
  • High pollution environments (class IV)
  • Compact substations and pole-mounted installations

Not Recommended For

  • Indoor installations
  • Systems above 10kV
  • Gas-insulated switchgear (GIS)
  • High-frequency or DC applications

Topology & Wiring

For combined transformer: ground the secondary winding at one point. For CT: never open-circuit the secondary while energized - hazardous voltage. Use terminals 1S1/1S2 for protection winding, 2S1/2S2 for metering. For VT: never short-circuit the secondary while energized - dangerous overcurrent. Use terminals 1a/1n. Follow IEC 61869 / IEEE C57.13 conventions.

Standards & Compliance

  • Type Test Report: [On Request]
  • Calibration Certificate: [On Request]

Burden & Error Calculation (IEEE C57.13)

S_total = ΣS_instrument + I₂² × (ρ × 2L / A)

  • If S_total < 0.25 × S_rated: add compensation burden to maintain accuracy.
  • If S_total > S_rated: accuracy class cannot be guaranteed.

Product Overview

About This Product

JLSZV8-10W

This is a 10kV outdoor three-phase combined instrument transformer in which current and voltage functions share a single dry epoxy resin body, so the insulation structure itself defines the installation envelope rather than a separate oil or gas system.

The windings are cast in epoxy resin, giving a solid insulation system for outdoor service in pollution class IV. Accuracy classes 0.2(S) and 0.5 are available, with rated outputs of 10 or 15 VA at COSΦ=0.8 depending on the ratio selected; the unit weighs 60 kg. Ratios span 5/5-75/5, 100/5-200/5, 300/5 and 400/5-600/5, with short-time thermal and dynamic ratings stated per ratio on the nameplate and datasheet. The design follows GB/T 17201, and calibration or type-test documentation for metering settlement can be supplied [On Request].

It suits outdoor metering and measurement points on 10kV distribution feeders and renewable collector or storage step-up circuits. Observe the terminal diagram, earth the secondary at one point, and never open-circuit an energized CT secondary or short-circuit an energized VT secondary. It is not intended for voltage levels above 10kV. Ratio and accuracy customization, documentation packages and delivery schedules are quoted on request. ⚠️ Safety: Follow the nameplate terminal diagram and ground the secondary winding at one point.
